A neck-hanging massaging device 10 according to embodiments of the present disclosure will be described with reference to FIGS. 1 to 7 in the following.

Referring to FIGS. 1 and 2, the neck-hanging massaging device 10 may include an elastic arm 11, a first handle 12, a second handle 13, an electrode assembly 14 and an electric pulse generating device 15. The first handle 12 and the second handle 13 may be fixedly connected to the ends of the elastic arm 11 respectively. The electrode assembly 14 may be arranged on the elastic arm 11. The electric pulse generating device 15 may be electrically connected with the electrode assembly 14. The electric pulse generating device 15 may be arranged in the first handle 12.

In order to facilitate operation, according to some embodiments of the present disclosure, as shown in FIGS. 1 and 2, the neck-hanging massaging device 10 may further include a remote control device 16. The remote control device 16 may be magnetically attached to the first handle or the second handle, and thus the remote control device 16 may be prevented from being lost.

As shown in FIG. 3, the elastic arm 11 may include a first outer shell 111 and a first inner shell 112. The first inner shell 112 may be buckled with the first outer shell 111. Specifically, a groove 113 may be formed in one of the first outer shell 111 and the first inner shell 112, the other of the first outer shell 111 and the first inner shell 112 may be provided with a protrusion 114, and the protrusion 114 may be arranged in the groove 113, so that the first outer shell 111 and the first inner shell 112 may be connected conveniently. In some embodiments, in order to assemble the first outer shell 111 and the first inner shell 112 more stably, the first outer shell 111 and the first inner shell 112 may be further bonded through an adhesive.

In some embodiments, the first inner shell 112 may be made of silicone rubber so as to be attached to the skin conveniently and make people feel comfortable. In addition, compared with plastic materials in the art, friction force between the elastic arm 11 and the human neck skin may be increased through contact of the silicone rubber and the skin, thus, the massaging device 10 may twist along with twist of the human neck. Thus, the massaging device 10 according to the embodiments of the present disclosure may be attached to the human neck more comfortably and stably, and the acmesthesia feeling caused by the electrode assembly 14 occasionally when detaching from the skin of a user may be avoided accordingly.

In addition, as shown in FIG. 3, the space between the first outer shell 111 and the first inner shell 112 may be filled with a third sponge 115. In this way, the elastic arm 11 may be fuller, and the skin comfortableness may be further increased.

As shown in FIG. 5, the first handle 12 may include a second outer shell 121 and a second inner shell 122, and the second inner shell 122 may be buckled with the second outer shell 121. In some embodiments, the second outer shell 121 and the second inner shell 122 may be both made of plastic. Therefore, the electric pulse generating device 15 in the first handle 12 may be better protected, and when the neck-hanging massaging device 10 may be used, the electric pulse generating device 15 being damaged due to deformation of the first handle 12 may be avoided.

As shown in FIG. 4, the second handle 13 may include a third outer shell 131 and a third inner shell 132. The third inner shell 132 may be buckled with the third outer shell 131. A battery 17 may be mounted in the second handle 13. In some embodiments, the third outer shell 131 and the third inner shell 132 may be both made of plastic. Therefore, the battery 17 in the second handle 13 may be better protected, and the situation that when the neck-hanging massaging device 10 may be used, the battery 17 may be damaged due to deformation of the second handle 13 may be avoided. The electric pulse generating device 15 and the battery 17 may be mounted in the first handle 12 and the second handle 13 respectively, so that the weight of the neck-hanging massaging device 10 may be balanced, and stable wearing may be facilitated.

According to some optional examples of the present disclosure, in order to increase the comfort, the first handle 12 may further include a first silicone rubber sleeve 123, as shown in FIG. 5. The shape of the first silicone rubber sleeve 123 may be substantially the same as that of the second inner shell 122. The first silicone rubber sleeve 123 may be attached to the outer surface of the second inner shell 122. Similarly, the second handle 13 may include a second silicone rubber sleeve 133, as shown in FIG. 4. The second silicone rubber sleeve 133 may be attached to the outer surface of the third inner shell 133.

Further, referring to FIG. 5, a first sponge 124 may be attached to the inner surface of the second inner shell 122. The first sponge 124 may be located between the second inner shell 122 and the electric pulse generating device 15. In this way, the electrical pulse generating device 15 may be buffered and protected, and the hand feeling during attaching to the electrical pulse generating device 15 may be improved. Similarly, a second sponge 134 may be attached to the inner surface of the third inner shell 133, as shown in FIG. 4.

When the neck-hanging massaging device 10 may be used, the second handle 13 and the third handle 14 jointly grip the human neck. In some embodiments, in order to prevent the second handle 13 and the third handle 14 from squeezing the carotid artery of the neck, as shown in FIG. 5, the middle of the second inner shell 122 may be recessed inwards to form a first recessed portion 1221. First protrusion portions 1222 may be arranged at the two ends of the first recessed portion 1221, as shown in FIG. 5. The first recessed portion 1221 may be used to keep away from the carotid artery. Similarly, as shown in FIG. 4, the middle of the third inner shell 132 may be recessed inwards to form a second recessed portion 1321. Second protrusion portions 1322 may be arranged at the two ends of the second recessed portion 1321, as shown in FIG. 4.

According to some embodiments of the present disclosure, the first handle 12, the second handle 13 and the elastic arm 11 may be designed in a split mode. Specifically, as shown in FIG. 1 and FIG. 2, the first handle 12 may be connected with the elastic arm 11 through a collar 18. The second handle 13 may be connected with the elastic arm 11 through a collar 18. The collars 18 may prevent the first handle 12 and the second handle 13 from being deformed along with the elastic arm 11, and therefore electrical elements in the first handle 12 and the second handle 13 may be protected accordingly. To further increase the rigidity of the first handle 12 and the second handle 13, electrical elements, such as the electric pulse generating device 15 and the battery 17 etc, may be mounted through a rigid supporting members 125, 135 respectively.

In some embodiments, as shown in FIGS. 1-3 and FIGS. 6-7, the electrode assembly 14 may be of a long-strip shape. The electrode assembly 14 may be arranged in the extending direction of the elastic arm 11 as shown in FIGS. 1-3 and FIGS. 6-7, so that the electrode assembly 14 may be better attached to the human neck, and the acmesthesia feeling caused by the electrode assembly 14 occasionally when detaching from the skin may be avoided.

When the neck-hanging massaging device 10 may be assembled, the electric pulse generating device 15 may be mounted in the first handle 12 at first, and the battery 17 may be mounted in the second handle 13. Then, the second outer shell 121 and the second inner shell 122 may be buckled together, and the third outer shell 131 and the third inner shell 132 may be buckled together. Then, the first outer shell 111 and the first inner shell 112 may be buckled together. Finally, the first handle 12 may be connected with the elastic arm 11 through the collar 18, and the second handle 13 may be connected to the elastic arm 11 through the other collar 18.

When the neck-hanging massaging device 10 may be used, a user may hold the first handle 12 and the second handle 13 and separate the first handle 12 and the second handle 13 to a certain angle, so that the elastic arm 11 may be elastically deformed. Then, the neck-hanging massaging device 10 may be put on the neck, and the electrode assembly on the elastic arm 11 may be attached to the neck. Finally, the user may slowly release the first handle 12 and the second handle 13. At this time, depending on the resilient force of the elastic arm 11, the first handle 12 and the second handle 13 may clamp the neck. Since the resilient shape of the elastic arm 11 may adapt to the size of the necks of different users, the electrode assembly 14 may be well attached to the skin, and the acmesthesia feeling may be avoided. It should be pointed out that when the size of the neck of the user may be small, the elastic arm 11 may be completely restored without generating elastic force, and the first handle 12 and the second handle 13 may not clamp the neck accordingly.

Further, by arranging the electric pulse generating device 15 on the first handle 12 and the battery 17 on the second handle 13, the size of the elastic arm 11 may be prevented from being too large, and the weight of the whole neck-hanging massaging device 10 may be balanced. Under the gravity of the first handle 12, the second handle 13, the electric pulse generating device 15 and the battery 17, the electrode assembly 14 may be comfortably attached to the neck.

According to the neck-hanging massaging device 10 according to the embodiments of the present disclosure, the electric pulse generating device 15 and the battery 17 may be arranged in the first handle 12 and the second handle 13, the elastic arm 11 may connect the first handle 12 with the second handle 13, a user may wear the neck-hanging massaging device 10 through deformation of the elastic arm 11, and the massaging device may well adapt to the size of the neck without damaging the electric pulse generating device 15. In addition, under the gravity of the first handle 12, the second handle 13, the electric pulse generating device 15 and the battery 17, the electrode assembly 14 may be comfortably attached to the neck without causing acmesthesia feeling. Moreover, the skin or hair of the user will not be caught at the joint between the left handle or the right handle and the main body. In addition, deformation of the elastic arm 11 may depend on the form change of the elastic arm 11 itself, rather than the high non-deformable elastic force of the springs. Therefore, the elastic force of the neck-hanging massaging device 10 may make the user feel softer and more comfortable.

According to other embodiments of the present disclosure, as shown in FIG. 6, the elastic arm 21 may include a first outer shell 211 and a first inner shell 212, and the first inner shell 212 may be buckled with the first outer shell 211. The first handle 22 may include a second outer shell 221 and a second inner shell 222, and the second inner shell 222 may be buckled with the second outer shell 221. The second handle 23 may include a third outer shell 231 and a third inner shell 232. The third inner shell 232 may be buckled with the third outer shell 231. The first outer shell 211, the second outer shell 221 and the third outer shell 231 may be integrally molded.

In some embodiments, the first outer shell 211, the second outer shell 221 and the third outer shell 231 may be made of elastically deformable materials, such as plastic. However, since the overall structure formed by connecting the first outer shell 211, the second outer shell 221 and the third outer shell 231 may be approximately in a C shape, elastic deformation may be achieved to a certain extent, and in particular, the first outer shell 211 may have a higher elastic deformation degree.

In the embodiment, although the first outer shell 211, the second outer shell 221 and the third outer shell 231 may be integrally molded, collars 28 may still be arranged between the first handle 12 and the elastic arm 11 as well as between the second handle 13 and the elastic arm 11. According to an embodiment of the present disclosure, the first handle 12 and the second handle 13 may be prevented from being deformed with the elastic arm 11 through the collars, and therefore electrical elements in the first handle 12 and the second handle 13 may be protected.

The present disclosure may be not limited to the embodiments described herein, and the first outer shell 211, the second outer shell 221 and the third outer shell 231 may also be stainless steel sheets or the like.

According to further embodiments of the present disclosure, as shown in FIG. 7, in the neck-hanging massaging device 10, both the electric pulse generating device 15 and the battery 17 may be arranged in the first handle 12, and a counterweight 19 may be arranged in the second handle 13. The weight of the counterweight 19 may be substantially equal to the sum of the weights of the electric pulse generating device 15 and the battery 17. Therefore, the weight balance of the neck-hanging massaging device 10 may be ensured accordingly.
